The Yankees hurler had another MRI examination performed on Monday in Birmingham, Ala., meeting with Andrews to discuss the results and the upcoming procedure on Tuesday.
Yankees manager Joe Girardi said that the team has no timeframe on how long Wang will need to recover, but it will learn more after the surgery is complete.
"It's a tough loss for us," Girardi said after the Yankees' 6-2 loss to the Rays. "I feel for him, because he's been through a lot in the last 14 or 15 months, with the [right] foot injury and now this. Hopefully, this will be the end of the surgeries for him, and he will have the rest of his career to be healthy."
Wang has been on the disabled list since July 5, his second stint on the shelf this season. The right-hander finished the year 1-6 with a 9.64 ERA in 12 games (nine starts), exiting a July 4 start against the Blue Jays with what was diagnosed then as right shoulder tendinitis and bursitis.
The Yankees had hopes that Wang would return to the rotation, but he had to cut a July 20 tossing session short after feeling tenderness in his right biceps. He visited with both Dr. David Altchek and Yankees team physician Dr. Chris Ahmad to discuss the problem before seeking out Andrews, who also performed Wang's 2001 shoulder surgery.
"There were no complaints at all about his shoulder until he came out of the [July 4] game," Yankees pitching coach Dave Eiland said. "So there were no warning signs that we knew of."
Wang's recent history has been pockmarked by injuries. His season was cut short last year by a sprain of the Lisfranc ligament in his right foot, an injury sustained while running the bases on June 15 in Houston.
"He was on a roll last year when he hurt his foot, and he's meant a lot," Girardi said. "It's tough to see players go through this, but we'll be there for him and we'll help him get through this. We'll get him back pitching as soon as we can."
A 19-game winner in 2006 and '07, Wang also spent time on the DL this year from April 24-May 22 with weakness in the abductor muscles of both hips.
"It's been a long and frustrating year," Wang said on Friday. "With my foot injury and now my shoulder, I started off the season terribly. It's definitely frustrating."
